The Negros Island Region (Tagalog: Rehiyon ng Pulo ng Negros; Cebuano: Rehiyon sa Pulo sa Negros; Hiligaynon: Rehiyon sang Pulo sang Negros; Spanish: Región de Negros; NIR) is an administrative region in the Philippines. It includes the islands of Negros and Siquijor, and comprises the provinces of Negros Occidental, Negros Oriental, and Siquijor, along with the highly urbanized city of Bacolod, the region's most populous city. The regional centers are Bacolod and Dumaguete.

The region was originally established on May 29, 2015, comprising the provinces of Negros Occidental, Negros Oriental, and the city of Bacolod, all located on the island of Negros. However, the NIR was abolished on August 9, 2017. Nearly seven years later, the region was re-established on June 11, 2024, this time including Siquijor, an island province southeast of Negros that was previously part of Central Visayas.
